Application filed January 27, 1913. Serial No. 744,441.

To all whom it may concern:

Be it known that I, STEPHEN T. HILL, a

[citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Emery-Wheel Guards, of which the followingis a specification.

This invention relates to protecting devices for emery or other grinding wheels and the like, and its object is to provide a device of this kind which is very simple in construction and which can be readily adjusted to difierent heights above the wheel.

The invention also has for its object to provide a guard which is constructed so as invention is applied. The guard is in the shape of a hood comprising a curved top 6 and sides '7, dimensionedso as to fit over the wheel above the horizontal center line thereof. In the top of the hood is an opening 8 closed by a hinged plate 9. Thus, if a long piece of work is to be ground it may be inserted under the hood and its farther end passed through the opening, as shown by dotted lines in Fig. 2, after swinging the closure 9 open. At other times the plate 9 will be left closed. The hood is hinged at its rear end, as indicated at 10, to a base plate 11 mounted alongsidethe wheel 5 by being bolted to one of the bearings 12 of the shaft of said wheel. The base plate has a rearextens ion behind the wheel to which the-- hood is hinged.- This hinge connection enguard from the wheel.

heights above the wheel, and also swung entirely off the same if desired. For the purpose of holding the hood in adjusted position, there is provided a latch-bar 13 which is pivotedat one end, as indicated at 14, to one of the sides 7 of the hood, and has one of its edges notched, as indicated at 15. The latch-bar extends downward alongside the hood and. passes loosely through an aperture 16 in the base plate 11 with its notched edge engaging the edge of said aperture, whereby the latch-bar is held. Upon disengaging the notched edge, the hood may be swung on its hinge joint and adjusted within the limit of said edge, and when the latter is again engaged with the edge of the aperture. the hood is securely held in adjusted position.

The guard is simple and can be easily applied, no change in the wheel structure or its support'being necessary; The opening 8 enables a long piece of work to be operated on without necessitating the removal of the The hood has an extension or finger 17 at the hinge 10 which serves-as a stop to prevent the hood from dropping down on the wheel if the latch bar 13 should become ac-.

cidentally disengaged, said part 17 being adapted to engage the base plate 11 as shown in Fig. 2. andthus serving to luuit the downward swing of the hood.

I claim:

A guard for emery wheels and the like comprising a hood fitting over said wheel above the horizontal center line thereof, said.

hood having anopening in its to located to permit the insertion of a piece 0 work to be operated on, and a closure for said opening.
